Grace has been coming to Stinson every summer for the last 6 years, Mina the last 5.  They know their way around...the lagoon, the seals, the birds, the tides, Pt. Reyes Station, the town, and the National Seashore.  Being teenagers, they like to stay up late and sleep in...I said, "Do that at home next summer...not when we're renting a cottage at the beach!...Let's get outdoors!"
